It was dark when Ianto woke. Really dark, pitch dark. Much darker than it ever got in his flat. And the bed was a lot more firm than his. A bolt of panic shot through him, stiffening every sinew.
Then he felt something behind him shift and felt a warm, solid form press against his back. An arm curled over his chest and Ianto felt his body relax without his thinking about it, recognizing Jack's presence before his sleepy brain caught up. There was a half-murmur, half-grunt behind him and Ianto felt a spark of warmth in the deepest part of his body, a place that hadn't felt that way in a long, long time.
From somewhere outside came a rushing, swooping sound, accompanied by an echoing squawk. "Stupid bird," Jack muttered. Ianto couldn't help snickering. Jack's arm around him tightened and he felt Jack's nose and faintly-stubbled chin press against his neck.
He didn't quite know what this 'thing' was that they'd started, but he knew for definite that it was something good and something he hoped would continue for a long time. Ianto reminded himself to just enjoy whatever Jack offered, which so far was more than enough.
